Rubio's Coastal Grill in Coronado operates inside the Navy Exchange at Naval Air Station North Island, Building 2017, serving Baja-inspired fish tacos and coastal Mexican fare to military personnel and authorized base visitors. The chain was founded in San Diego in 1983 by Ralph Rubio after he brought the beer-battered fish taco north from Baja California, and this NASNI location extends that original recipe to the same military community that trains at facilities including the VADM Martin Fitness Center on the installation. The menu covers the signature Original Fish Taco alongside grilled gourmet tacos, California burritos, Mexican street corn bowls, shrimp burritos, and a 10-Taco Box built for group orders and command gatherings. Rubio's sources responsibly caught Wild Alaska Salmon, Alaska Pollock, and Mahi-Mahi for its seafood program, and the kitchen prepares "no-fried" pinto beans and handmade guacamole from scratch — a sourcing standard that echoes the ingredient-first ethos at specialty roasters such as Trident Coffee Coronado on Orange Avenue in the village. The fast-casual counter-service format runs breakfast through dinner with indoor and outdoor seating at the NEX complex, processing high-volume fish taco and burrito orders on a dedicated fry-and-grill line. Active-duty personnel and families stationed at Naval Air Station North Island on Coronado Island drive or walk from the base gate to reach this location, while mainland visitors cross the Coronado Bridge or ride the Coronado Ferry to the island's dining district.
